Protective Cover Y92A-48B/Y92A-48D The protective cover protects the front panel, particularly the time setting section, against dust, dirt and water drip, as well as prevents the set value from being altered due to accidental contact with the time setting knob. Y92A-48B Hard Plastic Cover Y92A-48D Soft PVC Cover Note: The Y92A-48B Protective Cover is made of a hard plastic and therefore, must be removed to change the timer set value. However, since the Y92A-48D Protective Cover is made of PVC, the set value can be altered by pressing on the surface of the cover. It may be, however, difficult to make setting changes of the Timer with the Y92A-48B Protective Cover attached, which must be taken into consideration before using the Y92A-48B Protective Cover. When attaching the Y92A-48A to the Timer to be panelmounted, use the Y92F-30 Mounting Adapter along with the Timer. The Protective Cover cannot be, however, used for the -FA Series. 9

Input Connections Signal Inputs Connect the start input contact between terminals and, the reset input contact between terminals and, the gate input contact between terminals and, and the check input contact between terminals and. Solid-state Signal Inputs Connect the start input transistor between terminals and, the reset input transistor between terminals and, the gate input transistor between terminals and, and the check input transistor between terminals and. For each signal input contact, use a gold-plated contacts with high reliability. Be sure that these input signals satisfy the following requirements: a resistance of 1 kω (max.) and a residual voltage of 1 V (max.) when the contact is made. For signal input, use an open collector type transistor with characteristics: V CEO = 20 V min., V CE(S) = 1 V max., IC = 50 ma min. and I CBO = 0.5 µa max. In addition, be sure that the input signals satisfy the following requirements: a resistance of 1 kω (max.) and a residual voltage of 1 V (max.) when the transistor is ON, and a resistance of 200 kω (min.) when the transistor is OFF. 10
From a solid-state circuit (proximity sensor, photoelectric sensor, or the like) with rated power supply voltage ranging from 6 to 30 VDC, input signals can also be applied by other than an open collector type transistor as shown in the following diagram. The input signal from a solid-state circuit is applied when output transistor Tr turns ON. In terms of signal voltage, the signal is input when it goes from a high to low level. Again, the residual voltage should be 1 V (max.) when the transistor is ON. As the current output from the timer to Tr is approximately 0.1 ma, this connection is possible provided the residual voltage is kept to a maximum of 1 V. Solid-state circuit (proximity sensor, photoelectric sensor, etc.) Note: Except for the power supply circuitry, avoid the laying of input signal wires in parallel or in the same conduit with hightension or power lines. It is recommended to use shielded wires or wiring with independent metal conduits for the shortest possible distance. -8H -8 ( ) ( ) 11

Precautions How to Change Operation Mode Operate the pushbuttons of the thumbwheel switch, located at the leftmost position on the front panel to set the operation mode. Eight operation modes (A, B, C, D, E, F, G, and H) are selectable and the selected operation mode is displayed in the operation mode display window. Note: The operation mode is fixed to A for -8H. How to Change Time Unit and Rated Time Operate the pushbuttons of the rightmost thumbwheel switch to select the desired time unit. Seven time units (0.1 s, s, 0.1 m, m, 0.1 h, h, or 10 h) are selectable and the selected time unit is displayed in the time unit display window. The desired rated time is specified by operating the three thumbwheel switches in the middle of the front panel. The range of rated time is 001 to 999 for each unit. Remaining time display The remaining time is displayed as a decreasing percentage between 0% and 100%. Connecting the Operating Power Supply The -8 contains a capacitor-drop power circuit. Use a sinusoidal power supply with a commercial frequency. Do not use power supplies with a high frequency component (such as inverter power supplies) for Timers with 100 to 240-VAC specifications. Using these power supplies can damage internal circuits. The power supply connections to the -A and -FA can be made without regard to polarity for both AC and DC power supplies; just connect to the specified terminals (2 and 10, or A1 and A2). When connecting a DC power supply to the -8 or -8H, however, the polarity must be connected as indicated. Although there is a wide range of power connectable to the -A and -FA, be sure that there is no inductive voltage or residual voltage applied to the timer power supply terminals (2 and 10, or A1 and A2) when the power switch is turned OFF. (Inductive voltage can be generated in the power supply line if it is placed in parallel with high-voltage or power lines.) A DC power supply can be connected if its ripple factor is 20% or less and the mean voltage is within the rated operating voltage range of the Timer. Connect the power supply voltage through a relay or switch in such a way that the voltage reaches a fixed value at once or the Timer may not be reset or a timer error could result. -8 and -8H Timers with AC specifications are equivalent to capacitor loads. When switching the Timer power supply with an SSR, use an SSR with a withstand voltage of twice the power supply voltage. Since the -8 and -8H Timers of AC specifications externally discharges a part of internal energy when the power is turned OFF, it may malfunction if an extremely sensitive relay is used with the following sequence circuit. If such a malfunction occurs, change the circuit configuration as shown below on the right side. X/a X/a Time unit selector T/b If malfunction is expected. T/b X/a Rated time display window 001 to 999 Rated time selector Time unit display window 0.1 s, s, 0.1 m 0.1 h, h, 10 h Time Unit and Rated Time Time unit Rated time 0.1 s 0.1 to 99.9 s s 1 to 999 s 0.1 m 0.1 to 99.9 m m 1 to 999 m 0.1 h 0.1 to 99.9 h h 1 to 999 h 10 h 10 to 9,990 h! Caution 1. Do not change the time unit, rated time, or operation mode while the timer is in operation. Otherwise, the timer may malfunction or be damaged. Be sure to turn off the power supply to the timer before changing the timer unit, rated time or operation mode. 2. Note that output will be generated in C, D, E, G, or H mode even if the rated time is set to 000. No output will be generated in A, B, or F mode. 14
Input/Output The operation of the output contacts varies with the operation specifications. Before making connections, check the operation specifications and operating conditions using the application examples provided. The -A and -FA do not use transformers. Simultaneous inputting power from two or more power supplies to separate timers or counters from a single input contact or transistor is not possible. For the power supply of an input device, use an isolating transformer, of which the primary and secondary windings are mutually isolated and the secondary winding is not grounded. -A/-FA Input terminal Power supply Circuit Rectifier circuit Isolation transformer is required. A transformer is not used in the power supplies for the -A and -FA. You can therefore receive an electrical shock by touching the input terminals when the power supply voltage is being applied. Take adequate precautions to protect against electrical shock. Inputs to input signal terminals are made by shorting the individual input terminals to the common terminal (terminal 3 for the -A or terminal (X) for the -FA). Internal circuits may be damaged if connections are made to any other terminals or if voltages are applied. If contacts are used to short the terminals, they will be switching a low voltage (approximately 5 VDC) and current (approximately 100 µa). You must therefore use high-reliability contacts with a contact resistance of 1 kω or less when shorted and residual voltage of 1 V maximum when shorted. The reset input will take priority if both the set and reset inputs are turned ON simultaneously. Others Holding relays are used for outputs on the -A Series. Dropping the Unit or otherwise subjecting it to shock can cause the relay to reverse or to move to the center position. How to Mount the Timer on Mounting Track When mounting a -FA Timer on a socket mounting track, observe the following procedures: Mounting First hook portion A of the timer to an edge of the track and then depress the timer in direction B. B A C Dismounting Pull out portion C with a round-blade screwdriver and remove the timer from the mounting track. 15
